During the Second World War, Italian East Africa was occupied by a British-led force including colonial and Ethiopian units.[4] After the war, Italian Somaliland and Eritrea came under British administration, while Ethiopia regained full independence. In 1949, Italian Somaliland was reconstituted as the Trust Territory of Somaliland, which was administered by Italy from 1950 until its independence in 1960.

Italian East Africa was briefly enlarged in 1940, as Italian forces conquered British Somaliland, thereby bringing all Somali territories under Italian administration. However, the enlarged colony was dismembered only a year later, when in the course of the East African Campaign the colony was occupied by British forces.[6]

Italian East Africa, in Italian "Africa Orientale Italiana", was acronymed in official documents as "AOI".[5]

Conquest of Ethiopia

Historians are still divided about the reasons for the Italian attack on Ethiopia in 1935. Some Italian historians such as Franco Catalano and Giorgio Rochat argue that the invasion was an act of social imperialism, contending that the Great Depression had badly damaged Mussolini's prestige, and that he needed a foreign war to distract public opinion.[7] Other historians such as Pietro Pastorelli have argued that the invasion was launched as part of an expansionist program to make Italy the main power in the Red Sea area and the Middle East.[7] A middle way interpretation was offered by the American historian MacGregor Knox, who argued that the war was started for both foreign and domestic reasons, being both a part of Mussolini's long-range expansionist plans and intended to give Mussolini a foreign policy triumph that would allow him to push the Fascist system in a more radical direction at home.[7]

Unlike forty years earlier, Italy's forces were far superior to the Abyssinian forces, especially in air power, and they were soon victorious. Emperor Haile Selassie was forced to flee the country, with Italian forces entering the capital city, Addis Ababa, to proclaim an empire by May 1936, making Ethiopia part of Italian East Africa.[8] Some Ethiopians welcomed the Italians and collaborated with them in the government of the newly created Italian Empire, like Ras Sejum Mangascià, Ras Ghetacciù Abaté and Ras Kebbedé Guebret. In 1937 the friendship of Sejum Mangascia with the Italian Viceroy Prince Amedeo, Duke of Aosta enabled this Ras to play an influential role in securing the release of 3,000 Ethiopian POWs being held in Italian Somaliland.

The Italian victory in the war coincided with the zenith of the international popularity of dictator Benito Mussolini's Fascist regime, during which colonialist leaders praised Mussolini for his actions.[9] Mussolini's international popularity decreased as he endorsed the annexation of Austria by Nazi Germany, beginning a political tilt toward Germany that eventually led to the downfall of Mussolini and the Fascist regime in Italy in World War II.[10]

Second World War and dissolution

East Africa Campaign northern front: Allied advances in 1941.

On 10 June 1940, Italy declared war on Britain and France, which made Italian military forces in Libya a threat to Egypt and those in the Italian East Africa a danger to the British and French territories in the Horn of Africa. Italian belligerence also closed the Mediterranean to Allied merchant ships and endangered British supply routes along the coast of East Africa, the Gulf of Aden, Red Sea and the Suez Canal. (The Kingdom of Egypt remained neutral during World War II, but the Anglo-Egyptian Treaty of 1936 allowed the British to occupy Egypt and Anglo-Egyptian Sudan.)[11] Egypt, the Suez Canal, French Somaliland and British Somaliland were also vulnerable to invasion, but the Comando Supremo (Italian General Staff) had planned for a war after 1942. In the summer of 1940, Italy was far from ready for a long war or for the occupation of large areas of Africa.[12]

In January 1942, with the final official surrender of the Italians, the British, under American pressure, signed an interim Anglo-Ethiopian Agreement with Selassie, acknowledging Ethiopian sovereignty. Makonnen Endelkachew was named as Prime Minister and on 19 December 1944, the final Anglo-Ethiopian Agreement was signed.

In the peace treaty of February 1947, Italy officially renounced sovereignty over its African colonies. Eritrea was placed under British military administration for the duration, and in 1950, it became part of Ethiopia. After 1945, Britain controlled both Somalilands, as protectorates. In November 1949, during the Potsdam Conference, the United Nations granted Italy trusteeship of Italian Somaliland under close supervision, on condition that Somalia achieve independence within ten years.[14] British Somaliland became independent on 26 June 1960 as the State of Somaliland, the Trust Territory of Somalia (ex-Italian Somaliland) became independent on 1 July 1960 and the territories united as the Somali Republic.[15]

Colonial administration

The colony was administered by a Viceroy of Ethiopia and Governor General of Italian East Africa, appointed by the Italian monarch. The dominion was further divided for administrative purposes into six Governorates and forty Commissionerships.[citation needed]

Economic development

In order to weaken the Orthodox Christian Amhara people who had run Ethiopia in the past, territory claimed by Eritrean Tigray-Tigrinyas and Somalis was given to the Eritrea Governorate and Somalia Governorate.[16] Reconstruction efforts after the war in 1936 were partially focused on benefiting the Muslim peoples in the colony at the expense of the Amhara to strengthen support by Muslims for the Italian colony.[16]

Italy's Fascist regime encouraged Italian peasants to colonize Ethiopia by setting up farms and small manufacturing businesses.[16] However, few Italians came to the Ethiopian colony, with most going to Eritrea and Somalia. While Italian Eritrea enjoyed some degree of development, supported by nearly 80,000 Italian colonists,[17] by 1940 only 3,200 farmers had arrived in Ethiopia, less than ten percent of the Fascist regime's goal.[18] Continued insurgency by native Ethiopians, lack of natural resources, rough terrain, and uncertainty of political and military conditions discouraged development and settlement in the countryside.[18]

The most important railway line in the African colonies of the Kingdom of Italy, the Djibouti-Addis Ababa long 784 km, was acquired following the conquest of the Ethiopian Empire by the Italians in 1936. The route was served until 1935 by steam trains that took about 36 hours to do the total trip between the capital of Ethiopia and the port of Djibouti. Following the Italian conquest was obtained in 1938 the increase of speed for the trains with the introduction of four railcars high capacity "type 038" derived from the model Fiat ALn56.[21]

These diesel trains were able to reach 70 km/h and so the time travel was cut in half to just 18 hours: they were used until the mid 1960s.[22] At the main stations there were some bus connections to the other cities of Italian Ethiopia not served by the railway.[23] Additionally, near the Addis Ababa station was created a special unit against fire, that was the only one in all Africa.[24]

However Ethiopia and Africa Orientale Italiana (AOI) proved to be extremely expensive to maintain, as the budget for the fiscal year 1936-37 had been set at 19.136 billion lira to create the necessary infrastructure for the colony.[16] At the time, Italy's entire yearly revenue was only 18.581 billion lira.[16]

The architects of the Fascist regime had drafted grandiose urbanistic projects for the enlargement of Addis Ababa, in order to build a state-of-the-art capital of the Africa Orientale Italiana, but these architectural plans -like all the other developments- were stopped by World War II.[25]

Demographics

Administrative subdivision of Italian East Africa.

In 1939, there were 165,267 Italian citizens in the Italian East Africa, the majority of them concentrated around the main urban centres of Asmara, Addis Ababa and Mogadishu. The total population was estimated around 12.1 million, with a density of just over 6.9 inhabitants per square kilometre (18/sq mi). The distribution of population was, however, very uneven. Eritrea, with an area of 230,000 km2 (90,000 sq mi), had a population estimated in about 1.5 million, with a population density of 6.4/km2 (16.7/sq mi); Ethiopia with an area of 790,000 km2 (305,000 sq mi) and a population of some 9.5 million, had a resulting density of 12/km2 (31/sq mi); sparsely populated Italian Somaliland finally, with an area of 700,000 km2 (271,000 sq mi) and a population of just 1.1 million, had a very low density of 1.5/km2 (4/sq mi).[26]

Atrocities against the Ethiopian population

In February 1937, following an assassination attempt on Italian East Africa's Viceroy, Marshal Rodolfo Graziani, Italian soldiers raided the famous Ethiopian monastery Debre Libanos, where the plotters had taken refuge, and executed the monks and nuns.[16] Afterwards, Italian soldiers destroyed native settlements in Addis Ababa, which resulted in 30,000 Ethiopians being killed and their homes left burned to the ground.[16][27] The brutal massacre has come to be known as Yekatit 12.[citation needed]

After the massacres, Graziani became known as "the Butcher of Ethiopia".[28] He was subsequently removed by Mussolini and replaced by Prince Amedeo, Duke of Aosta, who followed a more conciliatory policy towards the natives, obtaining a limited success in pacifying Ethiopia.[29]
